If I follow your "logic" to it's logical conclusion no traffic laws should be enforced until the smoke clears, and the bodies are tallied. Is that correct?
Not at all.
Look: Some states (Montana for instance) have NO speed limits on certain sections of the Interstate. Here in Cali, the speed limits range from 55-75 on the Interstates (depending on the population density).
We could reduce traffic deaths in the US to almost zero by reducing the speed limit EVERYWHERE to 30 miles per hour (and forcing people to wear personal air-bags). Doesn't mean that we SHOULD do that (although one of the arguments against raising the limit from 55 after the '73 oil crisis was that "Hey! Look how many lives have been saved!").
I'm certain that as a FReeper you wouldn't turn in your guns to the authorities simply because they argue that "one of them may accidentally go off and injure/kill/maim somebody", yet you are quite ready to go to jail after two beers just because the government says "you may accidently injure/kill/maim somebody".
